AIR GUN.

Application filed December 21, 1925. Serial No. 76,811.

This invention relates generally to air guns and rifles of the break-down type and consists of certain novel features of construction, combinations and arrangements of partsas will be more fully described and particularly pointed out in the appended claims. p

In the accompanying drawings: 1

Figure 1 is a side elevation of a gun em bodying my invention.

Figure 2 is an enlarged fragmentary vertical longitudinal sectional view through the gun. I

Figure 3 is a view similar to Figure 2 but "showing the stock in open position.

Figure & is a fragmentary top plan view with parts broken away.

Referring now to the drawing, 1- is the barrel, 2 is the stockand. 3 is the intermediate casing of a gun embodying my invention. As shown, the casing 3 is rigidly secured to the stock 2 and is pivotally connected to a substantially channel-shaped housing l rigidly secured to the barrel 1. To facilitate assembly of these parts, the barrel 1 is slotted to receive the housing 4, while the side walls of the latter are preferably slotted to receive the lower wall of the barrel, thus only one bolt 5 is required to secure the housing 4 to the barrel 1.

Pivotally mounted in the housing l, preferably adjacent to the bolt 5 is a trigger 6 having the vertically shaped forwardly extending projections 7 and 8, while slidably mounted in the-barrel 1 is the usual disc plunger 9 that is normally held in projected position by means of a coil spring 10. EX- tending through the convolutions of the spring 10 is a rod 11 that is rigidly secured at its forward end to the disc. plunger 9 that is provided at its rear end with a depending hook 12 which is adapted to travel in and be guided by the channel-shaped housing 4.

For drawing the plunger 9 rearwardly against the tension of the spring 10 to cock the gun, I have provided a pair of links 13 that are terminally connected to the stock casing 3 and to a transversely extending pin 15. As shown, a bolt 14: extends transversely of the casing 3 and engages aligned circular openings in the rear ends of the links 13, while the pin 15 rests on the upper edges 16 of the trigger housing 4 and engages elongated slots 17 in the forward ends ofthe links 13. t I

Heretofore a suitable abutmenthas been provided at the forward end of the barrel non, or PLYMOUTH, MICHIGAN, Assren'on 'ro MARKHAM AIR RIF E oorrto take the thrust :of the spring projected plunger when released'iby-the trigger, how ever such abutments are expensive tomanufacture in guns of this type. Whensuch abutments are dispensed with, the strains due to thrust areimparted by the links to the bolt 14. As a result these bolts bend into arcuate formand sometimes -rip or tear the walls of the casing 3. To take "care-0f the bending action relatively long bolts have to. be used. It is apparent therefore that 1 such a construction is also very objection-v lVith the present invention I have over-r come: the objectionable features just referred toby providing the side walls of the between the bolt i l-and forward ends of the slot 17 in the links, it is apparent that the projections 19 of the housing l will receive the shocks and strains when the hook 12 abuts the cross pin 15 after being released.

by the trigger and will thereby relieve the links 13 and bolt lt of such thrust and strains. Hence shorter bolts 14; may be used and damage to the casing 3 is obviated entirely. Moreover the construction is such that the cross pin 15 may be relatively short and may be readily removed and replaced whenever desired. The side walls of the barrel will prevent any accidental displacement of the pin 15 when the parts are assembled. It will also be apparent that the upper edges'16 of the housing 4: serve. asguides for the pin 15 while the projections 19 serve as abutments for both the cross pins 15 and coil spring 10. Thus from the foregoing description, it will be apparent that I have provided a strong and durable gun that is simple in construction and can be manufactured at a comparatively low cost.

While it is believed that from the foregoing description, the nature and advantage of my invention will be readily apparent, I desire to have it understood that I do v not limit myselfto What is hereinshown and described and that such changesinay be resorted to when desired as fall Within the Withsaid trigger controlledmeans including a cross pin engageable With the hook, and a link for actuating the pin,'-and means for relieving? said'link of strains and thrust.
